    Question of the Week

    I’m working on a project that would create the world’s largest American flag, using blooming trees to create the design from an aerial view. I’ve been leaning towards red and white crepe myrtles for the stripes as they have a long bloom time, but haven’t been able to pin down a tree with blue flowers. (Everything I search under ‘blue blooms on trees’ looks violet.) I’m willing to forgo using trees for the blue field plants if I must. But my biggest concern is having all three colors in bloom at the same time of the year, and the longer the bloom the better. Can you guide me in my search? Get the answer »
